Logitech is aware of this and we are working on updating Options and LCC software to ensure we comply with Apple’s guidelines and also to help Apple improve its security and reliability. The Legacy  System Extension message will be displayed the first time Logitech Options or LCC loads and again periodically while they remain installed and in use, and until we have released new versions of  Options and LCC.

    Bluetooth mouse or keyboard not recognized after reboot on MacOS (FileVault)
    If your Bluetooth mouse or keyboard does not reconnect after a reboot at the login screen and only reconnects after the login, this might be related to FileVault encryption.

    Potential solutions:
  • If your Logitech device came with a USB receiver, using it will solve the issue.
  • Use your MacBook keyboard and trackpad to login.
  •  Use a USB keyboard or mouse to login.
    Cleaning Logitech keyboards and mice

Before you clean your device:

  • Unplug it from your computer and make sure it’s turned off.
  • Remove the batteries.
  • Keep liquids away from your device, and don’t use solvents or abrasives.
    To clean your Touchpad, and other touch-sensitive and gesture-capable devices:
  • Use lens cleaner to lightly moisten a soft, lint-free cloth and gently wipe down your device.
    To clean your keyboard:
  • Use compressed air to remove any loose debris and dust between the keys. To clean the keys, use water to lightly moisten a soft, lint-free cloth and gently wipe down the keys.
    To clean your mouse:
  • Use water to lightly moisten a soft, lint-free cloth and gently wipe down the mouse.
    NOTE: In most cases, you can use isopropyl alcohol (rubbing alcohol) and anti-bacterial wipes. Before using rubbing alcohol or wipes, we suggest you test it first in an inconspicuous area to
    make sure it doesn’t cause discoloration or remove the lettering from the keys.
